97151 Behavior Assessment Billing — 2026 ABA Intake Documentation
CPT 97151 (Behavior identification assessment, administered by physician or qualified healthcare professional) is the ABA intake code that determines everything downstream — treatment authorization, hours approved, retro-billing eligibility.
What 97151 Actually Covers
- Initial diagnostic + functional behavior assessment
- Time-based unit billing (per 15 minutes)
- Assessment tools: PDDBI, VABS, SRS-2, ADOS-2, etc.
- Parent/caregiver interview time
- Report writing time (payer-varying — some include, some don’t)
Common 97151 Denials 2026
- Report writing time excluded — some payers deny time not spent face-to-face with client
- Missing standardized assessment tool — payer requires evidence of validated assessment
- Duplicate 97151 billing — usually once per treatment episode (varies by payer)
- Missing BCBA credentials — must be BCBA/BCBA-D, not BCaBA
